. Application filed January 4,1909. Serial No. 470,731.

To all whom it may concern:

Be it known that I, HARRY WILLIAMs, a citizen of the United States, andresident of New York, in the county of New York and State of New York,have invented certain new and useful Improvements in CombinationGas-Burners, of which the following is a specification.

My invention relates to gas burners; and it has for its object toprovide burners with an attachment which will permit the said burner tobe readily changed from an illuminating burner to a heater, or a burnerfor heating purposes, without necessitating the exchanging of theburners.

Referring to the drawing: Figure 1 is side elevation of my improvedcombination burner with the mantle attachment. Fig. 2 is a sideelevation (enlarged) of my combination burner, showing it as anilluminating burner. Fig. 3 is a side elevation (enlarged) of mycombinaton burner showing it as a heater or blue flame burner. Fig. a isa sectional elevation of the burner with-mantle removed. Fig. 5 is a topview of Fig. 4, showing the screen across the upper tube. Fig. 6 is adetached side view of the lower tube showing the right angled slot.

2 is the lower tube with central hole 6. Vithin this central hole, at ornear the bot tom is placed the cone 4, formed integral with tube andhaving opening 5 (see Fig. 4). The lower end of the tube 2, below thecone 4: is provided with internal threads as shown which permits of thetube being screwed upon any ordinary gas bracket (not shown). The tube2, at or near its lower end, is pierced with openings 3 cut around thecircumference of the same, see Figs. 1, 3, l, 6. One of these openings7, (see Fig. 6) is extended upward and the upper end provided with aright angled slot 8; the purpose of which will be described hereafter.Over the tube 2 is placed the outer tube 9, which is made to freelyslide on same. This outer tube is closed at the top 10; and the outersurface below the top edge (a certain distance) is pierced with a seriesof openings 12. The interior of the top 10 of tube 9 is provided with anannular groove 13. It is also provided with a hole to receive the tip14:. The object of the outer tube 9 is to open and close the orifices 3in the lower tube 2, for the purpose hereinafter described. But toinsure a tight fit of the outer tube 9 upon the tube 2, I enlarge thecircumference of the lower edge 15 of the tube 2, which will form awedge-like surface 16, effecting as the outer tube 9 presses over an airor gastight connection. Then again as the tube 9 closes orifices 3 oftube 2, the said tube 2, also closes openings 12 of tube 9. Now, as thetube 2 passes into annular groove 13, it will fit closely therein andproduce a tight fit which will prevent the gas passing same and escapingthrough holes 12. The interior of the annular groove may be suppliedwith packing to insure a more perfect fit.

The collar 19 is placed over outer tube 9, and is held thereto by screwpin 20; the threaded portion entering tube; and the unthreaded inner endpassing into the slot 8, (see Fig. 6). The collar 19 supports the ring22,by arms 23. Said ring is intended to supportutensils for heatingpurposes. When the burner is to be used for illuminating purposes, theouter tube 9 ispositioned as shown in Fig. 2. The gas in that casepasses up through tube 2 to the tip 14 and is burned therefrom. Theorifices 3 in tube 2 and openings 12 in tube 9, being closed, the gashas to pass up to tip, and burn therefrom, in the usual manner. Byraising the tube 9, (see Figs. 1, 3, 4), the orifices 3 and openings 12will be opened. The outer tube 9 is held up in place by the screw pin20, resting on edge of slot 8 (see Fig. eL-6). hen the orifice 3 isopened, the air rushes in and mixes with the gas in tubes, 29, thusproducing a gas for heating purposes; said gas passing out of opening12, where it is ignited. Thus, by simply raising or lowering the tube 9on tube 2, the burner may be readily converted from an illuminatingburner into a heater, without discarding any of the parts. The principleof this combined burner is not changed, when the commonly used Velsbachor mantle burner is attached. In that case, the mantle or upper cylinder30, is placed upon the top of tube 9, see Fig. 4. In order not tointerfere with the flow of the gas, out of orifice 12, I, at that point,enlarge the bore 31 of cylinder so as to allow the gas to freely pass upthe same to the mantle 32, which is supported by a collar 33, saidcollar passing over cylinder 30. The interior of the mantle cylinder 30,is provided with a screen disk 34. Suitable shoulders are formed on tube9 to support the mantle cylinder 3040 are brackets for supporting ashade (not shown) said brackets attached to the upper cylinder.

The change from an illuminating burner to a heater is instantaneous. Thegas coming out of orifice 12 is instantly ignited when the outer tube 9is raised by the flame of the tip 14, which flame is extinguished Whenthe gas coming out of orifices is ignited.

I ain aware that the cone 4 can be made closed at the top and havingorifices at or near the top, means for retaining the. outer tube inraised position, consisting of a screw pin passing through the casingand resting on a right angled slot cut in lower tube.

2. In a combination gas burner, a lower tube with a portion enlarged fora rest, orifices formed in the lower end thereof, and a conical plugwith a central opening, an outer tube closed at one end, said closed endprovided in the interior with an annular groove for the insertion of theupper end of the lower tube when outer tube is lowered, for the purposeof insuring a perfect airtight fit; said outer tube provided with aseries of openings at or near the top.

in a combination amm iewe'r tube having a centrally perforated conicalplug, orifices, formed'in'lower "end of said tube, and an enlargedbeveled portion for a rest, an outer tube with open lower end, and upperopenings, said outertube placed over the lower tube,-a collar placedaround the outer tube, means for holding the collar tothe said tube,consisting of a screw-pin,

and means'forj locking the outer tube in a raised position consisting ofthesaid screwpin threaded in the outer tube and having its inner endprojecting into a right-angled slot cut in the lower tube, and an upperor mantle cylinder provided with an enlarged bore, said cylinder placedover the'upper end of theouter tube.

4. In a combination gas. burner, lower tube with a bevel restandforifices, anouter tube placed over the lower tube, and resting uponsaid bevel rest to insurea tight fit, said outer tube provided with aclosed end, having an annular groove for the lower tube to pass into tolnsure at1ghtfit, said outer tube also provided with side openings,

an upper cylinder with enlarged bore, said cylinder placed over theouter tube, and a screen disk placed within the bore ofthe uppercylinder.
